All are the same on both sides:
Orange .50, Holiday Spa, Lg. Key
Lavender Roulette 2, Sahara Reno, Lg. Key
White roulette 2, Del Webb's Primadonna Casino, H&C
Orange ND, Barney's Casino, Lg. Key (the side shown has an extra partial stamp, with almost no gold--error? test chip?)

A question...the TCR lists some of the Stardust business card chips with white inlays and inserts, it lists others with blue inlays and inserts. This Robert Stella is described as having blue, we have a Mark Swain that looks the same but is described as having white. Are the descriptions inconsistent or do we have something not listed, or...?

TCR & C&W list a $2.00 Soper's Montgomery Lodge with 3 navy inserts. This chip has 3 dk. green inserts.

Thanks to Mark Erickson, I discovered that our Indians are attributed to The Chief, in Ely. TCR lists the beige one, but the brown and green ones aren't listed. C&W doesn't show any of these colors.
